 Phylogenetic analysis of the six internal gene segments of 2006–2007 A(H3N2). Phylogenetic trees were inferred and labeled as in Figure 1. Overall, the trees inferred from the internal gene segment revealed presence of the four major genetic clades, as obtained with the HA and NA segments (A–F). Noteworthy, M and PB1 phylogenies showed that clades B and D (A/Japan/7288/2007‐like and A/Brisbane/10/2006‐like), representing adamantane‐resistant viruses formed a single group; while viruses in groups B and C formed two distinct clades of adamantane‐sensitive viruses (A and C). See legend to Figure 1 for color codes.
